Problems solved by technology

[0019] However, at room temperature or when the data load input to the electrode is small, using a fixed voltage as the minimum value of the falling pulse input to the scan electrode will lead to the instability of the discharge mechanism and eventually lead to misdischarge or incomplete discharge, so Decrease the driving efficiency and brightness of the plasma display device, which will reduce the technical quality of the plasma display device.

Embodiment Construction

[0039] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0040]The plasma display device of the present invention includes the following parts: a plasma display panel equipped with a plurality of counter electrodes; among the plurality of counter electrodes, one electrode gradually drops from a first voltage to a second voltage and is completed by a first falling pulse. The first driving part; the second driving part that floats and drives the other electrodes in the counter electrode during the first falling pulse input period.

[0041] The above-mentioned plasma display device of the present invention floats and drives the sustain electrode during the initial fall period of the initial period. The reference for the plasma display device of the present invention to float the sustain electrode during the initial fall period is the temperature of the plasma display panel or the data loading of the plasma display panel.

Abstract

This invention relates to one plasma display device and its drive method, which makes the sustain electrode exerting voltage into initial process to adjust its impulse size and to improve brightness through adjusting impulse to avoid error discharge. This invention display device comprises the following parts: plasma display panel with multiple pairs of match electrodes with one gradually to second one from first impulse to the first drive part; second drive part to input first impulse into other electrode float drive in the input period.

Description

【Technical Field】 [0001] The present invention relates to a plasma display device and its driving method. During the initial (or start-up) period, the sustain electrode is involved in the initial process, and the size of the initial pulse during the initial period can be adjusted. Discharge ensures stable driving. 【Background technique】 [0002] In general, the partition between the front panel and the rear panel in a plasma display panel forms a unit, and each unit is filled with neon (Ne), helium (He) or a mixture of neon and helium (Ne+He) and other main discharges. Gas and inert gas containing a small amount of xenon. When a high-frequency voltage causes a discharge, the inert gas generates vacuum ultraviolet rays and causes the cells between the partitions to emit light to display images. Such a plasma display panel can realize a thin and light structure, so it is very popular as a new generation display device. [0003] Fig. 1 is a structural diagra...
